Shortly after checking in Saturday, Hensley said she got a call from the ship's staff saying they couldn't find their luggage or the dialysis machine.

"I said, 'My daughter cannot live without the dialysis,'" said Hensley. "They said, 'Well, then, get off the ship. You've got to get off the ship.' I said, 'I'm not leaving without her equipment and her supplies.'"

In a statement, Carnival said there was some question at the time that the dialysis machine made it on board.

"Given that it is imperative that Ms. Hensley have her dialysis equipment in order to sail, it was decided it would be in her best interest that she disembark the vessel," the statement read.

"I said, 'Without everything? You're giving me like a death sentence for my daughter,'" said Hensley.

But she said Carnival staff called security and escorted the family off the ship.

Hensley and her family were stranded in Miami without a ride back to Boynton Beach as the ship set sail with the dialysis machine and their luggage.

"Carnival Cruise Lines sincerely apologizes for this most unfortunate situation and is providing everyone in the Hensley party with a full refund of their cruise fare, as well as a credit for a future five-day cruise with Carnival," read a statement from Carnival.

Hensley is not mollified, however, and had to manually perform dialysis at home over the weekend until she could get to a dialysis center Monday.
